Reissued' Sept. 29, 1931 UNITED STATES PATENT OFFICE LIQUID CONTAINER I riginal No. 1,776,458, dated September 23, 1930, Seria1 No. 348,167, iled March 19, 1929. Application for reissue :ned November s, 1930. serial No. 494,437.

The present invention relates to improvements in liquid containers and more particularly to that type of container commonly known as a milk bottle or receptacle, but also 5 adaptable for otheruses, such as for ice cream, semi-liquid foods and the like.

The invention consists primarily in a tubular body and a closure therefor, preferably of compressed paper pulp structure sultably coated to prevent liquid penetration, and which may be cheaply manufactured and readily ,disposed of when its use is discontinued.

Among its objects, the present invention af- 'fords a container' bodyopen at its opposite ends and adapted for storage or being stacked in nested formation, enabling the conservation of space. Another object is thepfovision of a. groove adjacent an end portion of the 2 0 body wall which affords a circumferential reinforcement for the lower edge of the container, and maintains a closure member out of contact with the surface upon which the container rests, this being desirable for sanitary reasons. 4

A further object is to provide a closure member insertable into the container'through Y its open end and which has tight seating contact against the walls of the body by resiliency `of 1ts material, and therein maintained by seating upon the groove, and which is further forced into contact with said groove by the weight of the contents of the container.`

Withthe above mentioned and other 'objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the, claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more clearly comprehend the invention, referenceis directed to the accompanying drawings, wherein- Figure 1 is a view in verticalsection of a plurality of one embodiment of my improved i containers in nested formation.

adapted to support the closure member and Figure 2 is a similar view with a closure cap and bottom closure in position.

Figure 8 is a View in detail cross section of the' bottom closure. L

Referring more particularly to the drawings wherein like characters of reference designate corresponding parts, 1 indicates a tubular cylindrical body, open at its upper end at 2, andat its lower end at 3. The member l is preferably constructed of heavy paper, which is a well known product having suflicient liexibility for bending and forming, such as paraftlned stock, or is formed from paper pulp by any of the well known` meth'- ods, with its surface, particularly its inner surface, coated to preclude the admission of moisture thereinto. The tubular body'may be ofany suitable shape, but as illustrated the upper end of the body 1 is tapered at 4 and may be vertically ribbed at 5, the ribs aordf 79 ing 'strengthening means for the neck of the body. `n this form, the body member 1 slightly tapers or iares from a point below its neck to its bottom edge, enabling successive bodies, when their closures are eliminated from the ends, to be arranged in-telescopic or nested formation, as in Figure 1.

At its extreme upper end the body 1 is formed with a closure cap seat 6, o-n which is adapted to rest the peripheral edge of a conventional milk bottle closure or cap' 7.

Near its lower end the body l is circumferentially grooved at 8, the groove preferably opening on the inner surface of the body and the corrugation of the wall of the groove 8 affording a circumferential reinforcing rib for the lower portion of the body 1. The groove is provided with a bottom wall portion 9 which may be of suitable form or shape ab for purpose of illustrating the interlocking .of closure 1n the groove is shown in the preferred embodiment with the bottom wall disposed at substantially right angles to the wall of the receptacle and is further provided with an upwardly and inwardly curved wall 10 connecting the outer peripheral edge portion of the bottom wall with the wall of the body 1.

The closure member comprises an inverted 10Q saucer-like disc 11, preferably of material which is sufficiently flexible to be readil formed by a die, and having suicient resi iency so that when it is formedit may be 5 slightly deformed and yet sprin back to its A' formed shape. rlhe disc 11 is o a diameter for snug reception of its peripheral portion into the groove 8. The body of said disc is formed with a crowned center top portion or plane 12, from the edge of which depends a circumferential wall or skirt 13 which, with relation to the crowned lane 12, is disposed substantially vertically, ut may be slightly inclined radially outwardly if a conical container body is used in conjunction therewith. The closure wall or skirt 13 of the disc is curved in cross section preferably to corree spend with the cross sectional curvation of the groove 8, so that when the closure is placed within the end portion of body 1 the vertical portion of the skirt by reason of the above mentioned resiliency snugly contacts with the inner surface of the wall of body 1 immediately above the groove 8, as in Figure '5 2. The disc 11 is inserted in position by slightly distorting the saine and forcing it upwardly into the body 1 through its open end, the edges of th'fdisc springing into place, as in Fi re 2, thus reinforcing the bottom portion o the body 1; and the spring action or resiliency of the material, superinduced by the crowned plane 12 of the disc, exerts a pressure radiall outward of the vertical portion bf the skirt 13, including the curved portion Vthereof within the groove 8,

so that a leak-proof contact is formed between the disc andc'ontainer body 1.

As the receptacle receives its contents, the weight of the contents added on the crown center tends to force the same into a horizontal plane, and in doing so more tightly forces the skirted portion of the disc against the wall 1 and into the groove 8. When the container is used for a dry commodity, it may be disassembled and used a succeeding time, but it is designed preferably for ready disposal after being used for a wet commodity, and without a serious` financial loss to the user.

1. A liquid container comprising a tubular container body of rigid structure having a frustum conical upper portion superposed on a cylindrical lower portion, which lower portion is provided in its wall near and in spaced relation to its open bottom with a circumferential groove opening inwardly into the container, said groove provided with a bottom wall disposed at substantially right angles to the wall of the receptacle, and further provided with an upwardly and inwardly curved wall connecting the outer edge of the bottom wall of the groove with the container wall, a disc-shaped bottom closure having a crowned center and peripherally flanged to correspond to said groove, said bottom closure adapted for insertion into the container through its bottom.
